How to set setresourcelimit https://www.php.net/manual/en/imagick.setresourcelimit.php

Thanks for reporting. There is currently no way to call this method with this library. I will look into this, how this could be solved.

I think the best way is to do this configuration outside of this library for Imagick directly in the policy.xml.

Something like this.

<policymap>
  <policy domain="resource" name="memory" value="256MB"/>
  <policy domain="resource" name="map" value="512MB"/>
  <policy domain="resource" name="disk" value="1GB"/>
  <policy domain="resource" name="file" value="768"/>
  <policy domain="resource" name="thread" value="1"/>
</policymap>

See Imagick Documentation for further details.
